SCP: Containment Breach (itch)

SCP - Containment Breach is a first-person indie survival horror game. It's based on the SCP Foundation Wiki.

You play as D-9341, one of many Class-D test subjects used by the SCP Foundation, a foundation dedicated to containing and protecting anomalous creatures and artifacts from the rest of the world. The game begins with D-9341 waking up and being pulled from his cell to begin the test. However, during testing, the facility began malfunctioning, resulting in a site-wide containment breach.
